Fukushima reactors too “hot” to allow workers to look for molten nuclear cores
Hemisphere facing generations of radiologic contamination” from Fukushima — TV: It’s a major humanitarian crisis — NYT: “Nobody really knows” if 100s of tons of plutonium & uranium fuel resolidified — Experts: It’s certain reactor cores ‘moved around’; “Flowed to different part of buildings”? (VIDEO)
Al Jazeera, June 17, 2014: Fukushima ‘ice wall’ looking more like a dirt Slurpee […] Skeptics of the plan to build a massive ice wall […] didn’t have to wait particularly long for their first “I told you so.” […] “We have yet to form the ice stopper because we can’t make the temperature low enough to freeze water,” a TEPCO spokesman said. […] What if freezing causes the ground to sink? What if the ice and the ensuing expansion and contraction interrupts or further damages drainage in the reactor buildings? […] TEPCO’s experiment around the margins does nothing to address the hot mess at the core (as it were) of the crisis, and is cold comfort to those people still displaced or a country and hemisphere facing generations of radiologic contamination.
Christopher Morris, Muon Radiography Program Leader, June 16, 2014: “It’s certain that the reactor cores melted and the material moved around. By using muons going through the cores, we can make a radiograph of the uranium material and find out how much is left inside the pressure vessel, how much has leaked out of the pressure vessel.”
Duncan McBranch, Los Alamos Lab’s Chief Technology Officer, June 18, 2014: “The material itself may have melted and flowed to a different part of the building. Invasive techniques such as video endoscopy or introduction of robots run the risk of releasing radiation.”
New York Times, June 17, 2014: […] there are three wrecked reactor cores, twisted masses of hundreds of tons of highly radioactive uranium, plutonium, cesium and strontium. […] most of the material in the plant’s reactors resolidified, in difficult shapes and in confined spaces, wrapped around and through the structural parts of the reactors and the buildings. […] that is what the engineers think. Nobody really knows, because nobody has yet examined […] “nobody knows what happened inside,” [McBranch] said. “Nobody wants to go in to find out.” […] concrete, steel and water will all be distinguishable from uranium, plutonium and other very heavy materials. […] Testing will begin later this year, officials say, and final images will be produced next year.
KRQE, June 18, 2014: LANL technology to examine Fukushima damage […] “This is a major humanitarian crisis,” said Matt Durham, a post-doctoral researcher at Los Alamos […] “They are much too radioactive to go in and look at things,” said Christopher Morris, the lead researcher on the project. […] LANL hopes the detectors will be used in about a year. >> Full broadcast here
Fukushima ice wall project not working out too well
Fukushima operator struggles to build ice wall to contain radioactive water Tepco says it is behind schedule with scheme
because temperature of pipes sunk into ground is not low enough Agence France-Presse in Tokyo theguardian.com, Tuesday 17 June 2014 The operator of Japan‘s battered Fukushima nuclear power plant has said it is having trouble with the early stages of an ice wall being built under broken reactors to contain radioactive water.
Tokyo Electric Power (Tepco) has begun digging the trenches for a huge network of pipes under the plant through which it intends to pass refrigerant. This will freeze the soil and form a physical barrier that is intended to prevent clean groundwater flowing down mountainsides from mixing with contaminated water underneath the leaking reactors.
Tepco said on Tuesday that a smaller, inner ice wall whose pipes it sank earlier to contain the already-contaminated water was proving difficult. “We have yet to form the ice stopper because we can’t make the temperature low enough to freeze water,” a Tepco spokesman said.
“We are behind schedule but have already taken additional measures, including putting in more pipes, so that we can remove contaminated water from the trench starting next month.” The coolant being used in the operation is an aqueous solution of calcium chloride, which is cooled to -30C (-22F).
The idea of freezing a section of the ground, which was proposed for Fukushima last year, has previously been used in the construction of tunnels near watercourses.
However, scientists point out that it has not been done on this scale before, nor for the proposed length of time……http://www.theguardian.com/environment/2014/jun/17/fukushima-ice-wall-radioactive-water
Strange deaths of horses irradiated by Fukushima nuclear catastrophe
Japan Paper: “Horses became weak and died, one by one, from an unknown cause” at farm in Fukushima — Farmer: “There is something seriously wrong going on… This country is going mad, I‘m sure something grave is going to happen” — 14 out of 15 newborn horses died last year (PHOTOS) http://enenews.com/japan-paper-horses-became-weak-and-died-one-by-one-from-an-unknown-cause-at-farm-in-fukushima-farmer-there-is-something-seriously-wrong-going-on-this-country-is-going-mad-i?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29
Kyodo News, June 14, 2014: Tadao Mitome feels a duty to continue capturing images of the area to document the effects of the nuclear disaster […] Mitome, 75, published a photo book titled “3/11 Fukushima: Hibaku no Bokujo” (“Stock Farm Exposed to Radiation”), documenting a farm in the village of Iitate and its dying horses. “People should do whatever they are capable of doing,” Mitome said […] Iitate, about 40 km away from the wrecked power plant, [farmer Tokue Hosokawa] defied the central government’s order to evacuate. […] After nearly two years, horses became weak and died, one by one, from an unknown cause. Some horses in Fukushima were also put to death and sent away for autopsies. Mitome said he felt as though the eyes of the killed animals were trying to tell him that they would never let human beings forget about the nuclear disaster. […] “There are things that I must let people in the world know,” he said.
World Network For Saving Children From Radiation, Feb. 27, 2014: Mr. Hosokawa again lost three of his horses this summer. […] “Since then, three more horses have died. This village is reaching its end […] I don’t feel good”, he said.
Evacuee from Iitate: “University of Tohoku dissected the dead horses […] there were apparent abnormal results from the analysis of the blood […] 3 more horses have died here this summer. Hosokawa must be in shock […] I have demanded the Ministry of Environment to inform us of the results. But they keep saying, ‘we don’t know anything yet’ […] why can’t they at least publish the results so far? Surely there must be something wrong if they can’t publish.”
World Network For Saving Children From Radiation: “There is something seriously wrong going on” -Hosokawa […] According to him, horses have fallen ill one by one within these short weeks […] a white miniature horse, had the worst condition. Its skin was badly damaged. The veterinarian doctor who accompanied us saw it and indicated the symptoms of damaged liver […] It had jaundiced eyes. The doctor was wondering why its knees were so wobbly. […] 15 foals have been born since the beginning of this year, but 14 of them died within a month, sometimes within a week. “I have lived with horses since I was a kid, but I have never seen anything like this. It’s not normal. I think radiation is responsible for this”. Hosokawa stresses the effect of radiation as a cause. […] we asked a public health control centre to check the blood of the miniature horse. The results were negative for transmitted diseases or nutrient deficiency. […] We were overwhelmed by Hosokawa’s ghastly expression on his face and stunned with a shock by the grave situation, which was beyond our imagination. “This country is going mad, I‘m sure something grave is going to happen”.
Strong protest movement opposes restart of Kagoshima reactors, Japan
Anti-nuclear activists ratchet up pressure to block restart of Kagoshima reactors June 14, 2014 Asahi Shimbun By MASANOBU HIGASHIYAMA/ Staff Writer KAGOSHIMA–More than 1,000 protesters assembled before the prefectural government building here June 13 to oppose moves to restart a local nuclear power plant.
If the Sendai nuclear plant in Satsumasendai, Kagoshima Prefecture, were to go back online, it would mark the nation’s first restart under new safety standards brought in after the March 2011 nuclear disaster in Fukushima Prefecture.
The rally, which organizers deemed a “critical phase” in their anti-nuclear efforts, coincided with the start of the prefectural assembly session.
“Governor, why don’t you pick a fight with the central government like the Hakodate mayor has done to protect the life and health of residents?” Satoshi Kamata, a noted nonfiction writer who has written extensively about labor and environmental pollution issues, barked through a loudspeaker.
Kamata, 76, was referring to a lawsuit filed in April by the Hakodate municipal government in Hokkaido to demand a halt to the construction of a nuclear power plant across the Tsugaru Strait in Oma, Aomori Prefecture.
“After serious problems of pollution in the 1970s, Japanese learned that their lives are more important than the nation’s economy. Why are we regressing to the same situation in the question of nuclear power?” asked Kamata, who flew in from Tokyo, where he regularly participates in a weekly anti-nuclear protest held outside the prime minister’s office.
Among the other participants were evacuees from the disaster at the Fukushima No. 1 nuclear power plant. The rally was organized by about 90 groups, including a local co-op.
The protesters submitted to prefectural officials a petition signed by about 120,000 people from across Japan in protest to the restart of the plant, which is operated by Kyushu Electric Power Co…….http://ajw.asahi.com/article/0311disaster/fukushima/AJ201406140025
Conflict of interest as new Commissioners joing Japan’s nuclear regulator
NRA conflict rule ignored by Abe administration
When the Democratic Party of Japan established the NRA, then–prime minister Naoto Kan implemented a rule to prevent conflicts of interest. It stopped anyone from becoming an NRA commissioner who had been employed by a nuclear organization in the three preceding years, which was defined as someone receiving $5,000 per year from the nuclear industry during that time period.
It appears that the Liberal Democratic Party has ignored that rule.
Post-Fukushima nuke watchdog outrages Japanese, Straight,com NRA appointee Satoru Tanaka’s financial ties to the nuclear industry provoke howls from environmentalists and opposition politicians by MARTIN DUNPHY on JUN 13, 2014 JAPAN’S PARLIAMENT, THE Diet, approved a controversial government appointee to the country’s nuclear watchdog agency on Wednesday (June 11).
Satoru Tanaka, a 64-year-old professor of nuclear engineering, will start his job as commissioner with the Nuclear Regulation Authority (NRA) in September.
The staunch supporter of nuclear power has deep ties to the nuclear industry and has accepted tens of thousands of dollars from affiliated companies over the years. Continue reading
Opposition to nuclear power is strengthening in South Korea
S. Korea faces strong opposition to nuclear power SEJONG, June 15 (Yonhap) — The South Korean government is facing a renewed opposition against nuclear power plants sparked by the recent tragic sinking a passenger ferry while the need for what is considered the cheapest source of power is growing, government officials said Sunday.
The opposition against nuclear power plants gained a new momentum on raised public awareness for safety following the April 16 sinking of the passenger ferry, Sewol, in which 292 people have been confirmed dead with 12 still unaccounted for.
Those who have long opposed nuclear power are again pointing their fingers at nuclear power plants as the most hazardous facilities, which, they claim, could cause a far greater and more devastating tragedy than the ferry sinking should there be any accident, according to the government officials, who spoke on condition of anonymity.
Such a sentiment was also seen in recent remarks by Rep. Park Young-sun, floor leader of the main opposition New Politics Alliance for Democracy, who said, “Nuclear power plants are now said to be the largest threat to safety in our society after the sinking of the Sewol.”
Already, environmental groups are demanding the government decommission a nuclear reactor at Wolseong Nuclear Power Plant, which is currently undergoing review for a possible extension of its lifespan. The initial 30-year lifespan of the reactor located some 400 kilometers southeast of Seoul expired in November 2012……
Fukushima’s scattered melted nuclear cores are not found nor being dealt with

Radio Forum #72, May 24, 2014 — Translated by DISSENSUS JAPAN, June 10, 2014:
- Jiro Ishimaru, host: They don’t even know where the melted fuel is. What is the current situation of the melted fuel?
- Hiroaki Koide, professor at Kyoto University Research Reactor Institute: Nothing has been done. I don’t think the melted fuel is sitting in one piece as TEPCO and the government imagine. Probably, many pieces are scattered everywhere in the reactor vessel. For example, there are pieces stuck to the wall, I think. If, for example, they somehow can collect 50 pieces of debris they can’t collect the other 50; if many workers are forced to be exposed to radiation to do this ineffective job, I think it’s better to just contain it like the Chernobyl sarcophagus.
- Ishimaru: It is going to be a long road to decommissioning…
- Koide: The government says it will take 40 years, but that is not going to be enough at all. When they finish, I will have been dead for a long time.

Individual shareholders in Japan push for withdrawal from nuclear power
Individual Shareholders of Japan Nuclear Power Plants Want Reduced Reliance on Nuke Energy – Report International Business Times, By Esther Tanquintic-Misa | June 13, 2014 Individual shareholders of Japan‘s nuclear power plants want the government to review the country’s current energy mix to rely less on nuclear energy, a report by the Asahi Shimbun said. Shareholders of Tokyo Electric Power Co (TEPCO) want the company to evaluate and examine its Comprehensive Special Business
Plan.
The report noted individual shareholders of Japan‘s nine electric utilities with nuclear power plants had also submitted proposals to strengthen their call ahead of the June 26 annual general shareholders’ meetings of the power companies.
It was the first time that individual shareholders joined in the fray to push for a withdrawal of Japan’s dependence on nuclear power.
However, Asahi Shimbun believed their calls for major changes in policy would fall on deaf ears. These individual shares, when gathered, make up only a small number of total shares.
The bulk of the nine electric utilities’ shareholders belong to financial institutions and other corporate entities…….http://au.ibtimes.com/articles/555644/20140613/shareholders-japan-nuclear-power-plants-reliance-nuke.htm#.U5z0IJRdUnk

- Hiroaki Koide, professor at Kyoto University Research Reactor Institute: […] In November 2013, they started with Reactor #4 because it was the most accessible pool, and the most dangerous. The floor that housed the Used Fuel Pool in Reactor #4 was hugely damaged and it has been feared that the pool might collapse in any time. This is a very dangerous job. Any scale of accident is possible. But they have to do it. […]

Japan joins scramble to sell nuclear technology to India, despite Liability Law
Japan wants slice of nuclear pie, warms up to liability law Indian Express, by Subhomoy Bhattacharjee , Anil Sasi | New Delhi | June 12, 2014 While Toshiba owns US-based reactor manufacturer Westinghouse, Hitachi is a partner of GE’s reactor business. The deadlock on the liability issue, which had stonewalled progress on the operalisation of nuclear pacts that India had signed with global reactor vendors, is on the verge of being broken.
Japan could offer Prime Minister Narendra Modi a nuclear deal in the civil sector when he travels to Tokyo next month, Hiroshi Hirabayashi, former Japanese ambassador to India and now adviser to Prime Minister Shinzo Abe, indicated.
Russia too is reported to have communicated an “in principle” nod to the Indian nuclear liability law, paving the way for signing a contract for the setting up the third and fourth units of the Kudankulam Nuclear Power Project…….
Japan is a key player in the operationalisation of the commercial nuclear pacts signed by India. Japanese companies are major players in two of the four reactor vendors that have signed preliminary agreements with India for supply of equipment for imported Light Water reactor-based projects planned on coastal sites.
While Toshiba owns US-based reactor manufacturer Westinghouse, Hitachi is a partner of GE’s reactor business.The government has short-listed Toshiba-Westinghouse’s ‘AP1000’ reactors, GE-Hitachi’s ‘ESBWR’ reactors, along with French firm Areva’s EPRs and the Russian firm Atomstroyexport’s ‘VVER’ series reactors, which are already being deployed at Kudankulam. http://indianexpress.com/article/business/business-others/japan-wants-slice-of-nuclear-pie-warms-up-to-liability-law/
Melted reactor cores might now be exposed, as water levels fall in Fukushima nuclear reactors

NHK WORLD, June 9, 2014: TEPCO: Water in reactor half expected level— Officials with the operator of the damaged Fukushima Daiichi nuclear plant say the water level inside the No.2 reactor’s containment vessel is about half what they had estimated. […] They found the water was around 30 centimeters [11.8 inches] deep. TEPCO officials […] say they don’t know whether the fuel is entirely submerged. […] They believe then flowing out of the reactor building through holes in the chamber.
NHK WORLD, June 10, 2014: TEPCO officials are struggling to find […] the condition of the melted fuel […] Officials believe that at reactor number 2, water is leaking […] at the bottom of the containment vessel, but do not know exactly from where. [At] reactors 1 and 3, the utility has found the sources of some leaks, but suspects there are other breaches […] Nothing is known about the condition of the melted fuel in all 3 reactors. TEPCO is considering various forms of surveys, including a plan to send a camera-mounted robot […]
Kyodo News, June 9, 2014: TEPCO confirms water level of Fukushima No. 2 reactor container […] A TEPCO official [said] the detailed condition of the melted fuel remains unknown.
NHK Transcript, June 9, 2014:
- Officials at Tepco are facing another setback.
- They don’t know whether [the water] even covers all of the nuclear fuel.
- Officials don’t know about the condition of the melted fuel.
- Officials believe the water level at another reactor is 10 times deeper.
- Teruaki Kobayashi, Tepco official: “We cannot tell at this point if the fuel is entirely submerged or if part of it’s above the water.”

India’s nuclear liability law poses a challenge to Russia-India nuclear power agreement
Russia agrees on India’s nuclear liability law http://economictimes.indiatimes.com/industry/energy/power/russia-agrees-on-indias-nuclear-liability-law/articleshow/36359852.cms MOSCOW: Russia has in principle agreed on the Indian nuclear liability law, paving the way for signing a contract for unit 3 and 4 of the Kudankulam Nuclear Power Plant in July, Russian officials said today. “The (liability) law enacted is certainly challenging. We are working with our colleagues (counterparts) in India and the issue has been resolved,” said Kirill Komarov, Deputy Director General on Development and International business, Rosatom State Corporation. “We have just signed the protocol. The approvals will take some time. We have are awaiting nod from the Indian side. The India’s over view authority (Atomic energy Regulatory Board) is yet to give its nod. “They are also checking seismic activity in the area. So by July we should be ready with a roadmap after which we can start implementing the General Framework Agreement signed between the two countries,” said told a press conference. Unit 1 of the KKNPP has attained 100 per cent capacity of 1000 MW while the second unit should start generating power from this year. Units 1 and 2 of Tamil Nadu-based Kudankulam Nuclear Power Plant (KKNPP) have been built with the help of Russian assistance at the cost of Rs 17,200 crore. Insuring nuclear power plants is a daunting task because of its high cost and there is no single governmental insurance entity in the country that can insure these installations .. .. http://economictimes.indiatimes.com/articleshow/36359852.cms?utm_source=contentofinterest&utm_medium=text&utm_campaign=cppst
India wants Russia to make Koodankulam Nuclear Power Plant safer
India Seeks More Security Measures for Koodankulam Nuclear Power Plant New Indian Express, By Prashant Rangnekar 9 June 14 MOSCOW: India has sought “enhanced security measures” for the Koodankulam Nuclear Power Plant after the Fukushmia Daichi atomic disaster in Japan, Russia said.
“This can lead to immediate stopping of chain reaction in case of crisis. The system will ensure water supply for cooling of the reactor even if there is a black out for 24 hours,” Asmolov said.
He was speaking at the sidelines of Atom2014 Expo, a conference organised by Rosatom, a Russian state atomic energy body……

Japan fudges its reporting to IAEA on plutonium
Japan underreports 80 nuclear bombs-worth of plutonium to IAEA Rt.com : June 08, 2014 Japan has failed to mention having about 640 kg (1,411 lbs) of unused plutonium in reports it submitted to the International Atomic Energy Agency (IAEA) in 2012 and 2013. The unreported amount is enough to make about 80 nuclear bombs.
The MOX fuel was loaded into the No. 3 reactor of Kyushu Electric Power Co.’s Genkai nuclear plant in March 2011 during its regular checkup, shortly before the Fukushima Nuclear disaster happened later that month. It was then taken out two years later as the reactor remained offline.
The unreported plutonium was first found by Kakujoho, a nuclear information website……..http://rt.com/news/164504-japan-nuclear-ieae-reports/
Corrosion of Fukushima’s melted nuclear cores is releasing more plutonium
Study: Water helps dissolve Fukushima’s melted nuclear cores, accelerates 
corrosion — Plutonium concentrates on outer edge of fuel — Poses “a much longer environmental threat” than initial releases — Transport of nuclear material into environment to continue for many years if not isolated http://enenews.com/study-water-helps-dissolve-fukushimas-melted-nuclear-cores-accelerates-corrosion-plutonium-concentrates-outer-edge-fuel-poses-longer-environmental-threat-initial-releases-transport-nuclear-ma?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29
‘Nuclear Fuel in a Reactor Accident’ — Peter Burns, Rodney Ewing, Alexandra Navrotsky, 2012: Seawater was injected into the three active reactors […] large amounts of salt may have deposited in the reactor cores. […] Nonuniform burn-up in a fuel pellet gives higher concentrations of 239Pu near the pellet edge […] the major potential pathway for continued release of radionuclides is through flowing water. […] Many radionuclides form aqueous complexes that are soluble in water. Furthermore, water promotes dissolution of the rod/fuel matrix, which releases radionuclides [that] pose a much longer environmental hazard […] The radiolytic breakdown of water creates oxidants (e.g., hydrogen peroxide) that can accelerate the oxidative corrosion of fuel […] If the water is alkaline, soluble nanoscale uranyl peroxo cage clusters are likely to form and persist in solution. […] there is no reliable way of predicting dissolution rates of damaged fuel in water under the conditions of a nuclear accident, especially one like Fukushima Daiichi in which fuel is exposed to hot or boiling seawater […] an understanding of the factors that determine radionuclide release is central to taking appropriate and timely action in order to minimize impacts on the environment and human health. […] Water that interacts with damaged fuel will transport radionuclides that present both short-term and longer-term environmental risk […] potentially continuing for many years if the damaged fuel is not adequately isolated […]
AAAS Science Podcast interview with Peter Burns about study:[…] it’s the interaction of the water and the air with that that is going to control the release of radioactivity to the environment […] what’s different about Fukushima relative to the earlier events is the vast quantities of water that were pumped into the reactor cores […] that created a whole new release pathway for radionuclides out of the reactors into the environment. We don’t know how much radioactivity was released through the water flow, and we don’t know very much about how the water interacted with the fuel and other structure materials. […] we need to take very seriously the development of knowledge about how […] melted nuclear fuel […] interacts with the environment, especially water that we might use in an emergency to cool it. Studies that have been done to date really haven’t looked at the longer-term interactions of water and the atmosphere with these damaged materials. […] as it interacts with water or whatever over time – [fuel] has a potential to release radionuclides that have much longer half-lives and they pose a much longer environmental threat.
